What is 38 × 9?

Answer

38 × 9 =
342

38 × 9 and 9 × 38 are the same product — the order of the factors never changes the answer, only the working. Below, 38 is multiplied by 9 in a column, digit by digit.

38 × 9 in a Column

The multiplicand goes on top, the multiplier underneath, both aligned on the right. The multiplier has a single digit, so there is one partial product and the answer goes straight under the line.

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 9: 38 × 9 = 342.

  • 8 × 9 = 72. Write 2 and carry 7.
  • 3 × 9 = 27, plus the carried 7 makes 34. Write 4 and carry 3.
  • No digits are left, so the carried 3 is written in front: the partial product is 342.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 342 ÷ 9 = 38 must come out exactly, with no remainder.

Fractions are a different calculation. Both factors here are whole numbers; for 2/3 or 2 3/4 use the fraction multiplication calculator, which multiplies numerators and denominators separately.

38 × 9 is a number, not an area. If those are the sides of a room in feet, the answer is 342 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.

Long Multiplication Calculator

This calculator multiplies two whole numbers the way it is done on paper: digit by digit, carrying where the column overflows, then adding the partial products together. For example, it can help you find out what is 38 × 9? (The answer is: 342). Enter the multiplicand (e.g. '38') and the multiplier (e.g. '9') and hit the button. The order of the two numbers does not matter — 38 × 9 and 9 × 38 are the same product — so either number can go on top. Fractions and mixed numbers belong to the fraction multiplication calculator, and the reverse operation is long division.
